X386 1.1; ProDesigner II + NEC 4D

Sat Feb 16 07:26:49 AEST 1991

X386 1.1
--------

If you're looking for the X386 1.1 binaries (exclusive of the fonts, but
they haven't changed anyway), I've already sent them to turing.cse.nau.edu
and will send them to atc.sp.unisys.com after I finish this message.  

ProDesigner II and NEC 4D 
--------------------------

You read and use the info below AT YOUR OWN RISK. 

As you may know, Thomas Roell's clock.pas, the way it's written, doesn't
detect the presense of the 44-MHz and 62-MHz crystals.  I called Orchid and
was told that the ordering of the crystals are "proprietary."  Luckily, some 
knowledge of binary numbers and a little trial and error straightened
the most important thing (see below) out.  The working parameters are:

     # Orchid ProDesigner II/1024
     ET4000   1024   1152 900   25 28 40 36 0 44 0 62 "1024x768" # Orchid Prodesigner II

Note that the "44" could be bogus, but since I wanted only 1024x768x256, I
didn't bother to check it out.  I think you can even say "25 28 40 36 0 62"
and make it work at 1024x768.

Now comes the interesting part.  Note that I didn't have all the documentation
I needed, so certain things were based on (very) educated (  :-)  ) guesses.
(It works perfectly on my ProDesigner II + NEC 4D--one doesn't even hear the
awful sound that switching frequencies sometimes produces.) 

I assumed the ProDesigner II syncs on green, as opposed to using separate
syncs as listed in its user's manual.  I set 4D's sync switch to OFF, and
computed the following numbers based on this assumption.  They are probably
as close to the 4D's spec as they can get.

     # Orchid ProDesigner II and an NEC 4D
     "1024x768"  62    1024 1071 1133 1327      768 769 773 799 

This is a genuine noninterlaced 1024x768 at 60Hz.  It flickers a bit, but 
it's hardly noticeable unless you have a window with a white background
(even then it's no worse than our HP's color board and SONY).  Note that
70Hz requires a 75-MHz crystal, according my calculation based on the NEC
4D manual.  Don't forget that Thomas gave us a virtual screen of 1152x900
here, so some clients might get clipped at the border; move the mouse cursor
to bring the hidden parts into view.

You don't necessarily get the correct aspect ratio by making the root
window's width/height 4/3.  Run "xfig," draw a circle, and adjust the
screen to make the circle look (and measure) like a circle to you.
